Using words how you know a fraction is equivalent to another fraction

You know because when you a number like 2/4 you simplify it which means divide it, you divide it by 2 to get 1/2

A simple way to look at how to check for equivalent fractions is to do what is called "cross-multiply", which means multiple the numerator of one fraction by the denominator of the other fraction. Then do the same thing in reverse. Now compare the two answers to see if they are equal.
